Abstract: 715,499. Road &c. scraping and levelling machines. LIMMER & TRINIDAD LAKE ASPHALT CO., Ltd., and OLDING & CO., Ltd., J. Jan. 26, 1953 [Jan. 24, 1952], No. 1936/52. Class 107 A road or like surface scraping, levelling and excavating machine comprises one or more ground engaging tools mounted for rotation about a vertical axis on a machine provided with power means for advancing the machine as well as for rotating the tools. The machine is provided with means for raising and lowering the tools and has an adjustable stop set by the operator to limit the downward movement of the tool or tools after they are raised. Fluid pressure means may be employed to raise and lower the tools and it is adapted to allow the tool to rise against the pressure of the working fluid if the reaction of the tool and the ground becomes excessive. An embodiment utilizing hydraulic means comprises a rotating tool assembly 12 rotating in, but non-slidably associated with. a sleeve 14 as disclosed in Specification 694,027 the shaft 11 of the tool assembly being driven, as for example as disclosed in Specification 715,498. The elevating sleeve carries a flange 15 to which are connected lugs 16 A piston rod 17 of a double-acting hydrau'ic piston- and-cylinder assembly 18 connects to one lug and is controlled by a four-way valve 22 to enable raising and lowering of the tool under the operator's control. A relief valve 26 re'ieves excess pressure in the hydraulic system and allows the tool to move upwards if undue resistance to the cutting action is encountered. The other lug 16 is connected to a flexible wire rope or other flexible tension-resisting member 27. The latter is fastened to a lever 28 having an abutment 31 with an adjustable screw 32 and thus the downward position of the tool can be controlled. Several tools each with its own control mechanism as described above may be fitted to the machine. An overload clutch such as described in Specification 715,498 may be fitted to the tool drives.

Abstract: 155,852. Roberts, E., and Mather & Platt, Ltd. Feb. 5, 1918. Automatic gear for starting and stopping.- Relates to means for automatically starting and stopping steam, fire and other pumps at predetermined intervals. The pump is started for service by ordinary means comprising a diaphragm valve o actuated by the pressure in a pipe r connected with the water main. The automatic gear for starting and stopping periodically comprises a pipe z with a back-pressure valve a<1> connected to the pump delivery, and provided with an air vessel 14, a water cistern t with a float-actuated valve u and drop cock 2, and connected by pipe 8 with a diphragm 9 controlling a small auxiliary steam valve 12 which by-passes the main steam valve. After the pump has ceased running and pressure exists in the main and the cistern t is full, the water drips at a rate determined by the setting of a cock 2. When the valve u is opened, the pressure on the diaphragm 9 is relieved, the valve 12 is opened, and the pump run to refill the cistern and restore the pressure. In a modification, the cistern is provided with two float valves which control two diaphragms having an auxiliary steam valve between them. In a further modification, the air vessel 14 and auxiliary steam regulating- valve are dispensed with, and the cistern is connected up to a pipe r and periodically reduces the pressure therein to actuate the main regulating valve o.

Abstract: 1,261,543. Resonant cavities. UNION CARBIDE CORP. 14 Jan., 1969 [30 Jan., 1968], No. 2111/69. Heading H1W. [Also in Division C7]  An A.C. superconducting device, e.g. an RF cavity, is made by depositing a superconducting layer upon a highly finished substrate which is subsequently removed. The Figure depicts an intermediate step in the electrodeposition of highly pure niobium upon a substrate 1 to form a tubular RF cavity 2. The substrate may be made of copper, nickel, iron or iron alloy and is polished to obtain an extremely smooth finish, e.g. a roughness less than 5 Á inches RMS. The deposition is carried out using a fused-salt bath consisting of KF, NaF, LiF and K 2 NbF 7 , the proportions of the constituents, temperature, current density &c. being chosen to obtain a dense, fine grain deposit. After the deposition slip, a layer 3 of a porous, refractory material having good thermal conductivity, is deposited over the electroplated niobium, e.g. by plasma plating, electroplating, vapour deposition or a powder metallurgy process. This layer may consist of molybdenum, tantalum, niobium, tungsten, graphite, indium, platinum or a ceramic.

Class 59 A portable mulling machine comprises a supporting frame with axially aligned spaced vehicular wheels, a stationary crib secured to said frame, and a rotatable muller head mounted in said crib to form with the crib and the frame an integral part of the overall machine, said frame, crib and muller. head being tiltable about the axis of said wheels. As shown, Fig. 3, the mulling unit comprises a crib 10 the bottom plate 12 of which coacts with muller wheels 14 mounted on rocker arms 18 which are journalled by means of bearings 20 to a crosshead 24 keyed to the motordriven shaft 41. The muller wheels may be adjusted relative to the plate 12 by adjusting screws 25 which bear against the crosshead whilst the pressure of the wheels on the sand in the crib may be varied by adjusting lock nuts 31 which control the tensioning of a spring 28 disposed in a telescopic housing 29. This housing connects the two rocker arms 18 by means of connectors 34 and arms 36. Plough member 37, Fig. 2, is arranged to scrape sand from the plate 12 and urge it outwardly into the path of the-muller wheels whilst plough 39 scrapes the plate 12 and sidewalls of the crib and urges the sand inwardly.

Jan. 23, 1933, No. 2186. Convention date, Jan. 23, 1932. [Class 38 (iii).] In a control system for a synchronous electric motor, the field winding of the motor is disconnected from its source of excitation when the motor falls out of synchronism by means responsive to the power factor of the motor.

Abstract: 968,041. Monitoring tyre pressures. GENERAL ELECTRIC CO. Ltd. Jan. 15, 1963 [Jan. 22, 1962], No. 2236/62. Heading B7C. A device 5, responsive to tyre pressure, controls contacts 6 in a circuit comprising coils 4, 7 and non-linear impedance 8 mounted on a rotating vehicle wheel. Electrical oscillations supplied by oscillators 2, 3 on the vehicle chassis (Fig. 1) are transmitted by electromagnetic coupling from stationary coil 1 to moving coil 4 when the coils are adjacent and, if contacts 6 are closed by an excessively low tyre pressure, the impedance 8 generates oscillations, of different frequency from those supplied, which are transmitted by electromagnetic coupling from coil 7 to stationary coil 9 and then through filter 10, amplifier 11 to actuate a detector 12, which gives visual or audible warning in the driving cab and may reduce the speed of the vehicle. In Fig. 1 oscillators 2, 3 supply two different frequencies (30, 40 kc./s.) which are heterodyned by the crystal diode 8 to produce a frequency (70 kc./s.) which filter 11 is tuned to pass. Coils 1, 9 and 4, 7 may be mounted adjacently on chassis and wheel, so that coils 1, 4 and 7, 9 couple at the same time during the wheel's rotation. Fig. 3 (not shown) illustrates an arrangement with only one coil each on chassis and wheel, to couple oscillations in both directions. The non-linear impedance may act as a frequency multiplier instead of a mixer, in which case only one oscillator is needed. On a vehicle, the oscillators, filter, amplifier and detector may be common to several wheels each having the coils, diode &c.
